As a bonus to stereo reception, most television sets can now provide a second audio program channel. This is in addition to the left/right stereo signals and is a separate audio source.

Use of the SAP channel can range from a duplication of what is on the main audio channels, a second language, descriptive information on the program, or material totally unrelated to what is being viewed. It is not uncommon to find that all of the these types of material are sent at one time or another during the broadcast day.

Television sets generally require the SAP channel be specifically selected to hear it. The method of selection is outlined in your owner's manual. If you can't find it, give the store you purchased it from a call. Most salespersons can help talk you through the set's selection process. Generally the SAP is either a mechanical switch labeled "stereo-mono-sap" or a menu accessed programing function that allows the same functions to be addressed.

TPT has pioneered the introduction of SAP to the Twin Cities area. Barely a day goes by without a viewer calling requesting information about "that strange audio" on our signal. While normally we transmit a copy of the main audio channel, at times we don't. I would encourage you to become familiar with your set's operation before SAP causes interruption to your viewing enjoyment. Once you've gotten the hang of switching back and forth, tune in, at times it is more than entertainment. Soon you'll be saying "what in the world are they doing now?"
